I put a new clutch disc and pilot bushing in my Super C while I had it split. Other than checking finger heights, and cleaning everything up I didn't mess with anything else. (T.O. bearing is good). Now it seems like the clutch is always engaged, even though I have plenty of free play. I can turn the axle by hand (it's on jacks) while the trans. is in gear. With the motor running it will engage & disengage the axle, but seems like it's slipping or something.

What should I check first?

Thanks
 
Nope, It was a long time age when I removed it, but I don't believe Rockford's have those.

I did a complete resto on the tractor, but I'm sure the rear-end went together correctly. As far as the clutch, just un-bolt the pressure plate, slip in the new disc & bolt back up. It seems if anything it should be tighter?
 
There are three bolts that are located around the reaward side of the new Pressure plate. These bolts hold the clutch in the released position. Meaning not driving the wheels, engine running, pedal down as far as it will go. Removing these bolts with the C together might not be possible, I do not know. But they are usually there. JimN
 
The drive shaft could be disconnected at the trans! (I was typing while you were answering the other post)If there is only neutral, you should be able to see into the hole in the torque tube where the clutch rod goes in to see what is turning. I assume the trans shifts into all gears like normal, but it does not have drive power. JimN
 
Are you sure you have the clutch plate in correct and not backwards. Have you adjusted the linkage so you have 1in free play before the throw-out bearing enguages the fingers. The Cs can have a lot of wear in the pedal shaft.
 
Possibility #2.
I do not know if what you describe is slipping, or free to turn, or no clutch driving the rear.
If you are turning one axle with it in gear, and with the pedal all the way up at the platform, engine off, and it seems to be slipping, did you look at the other axle? In a differential, the other axle will turn opposite direction and if not held, will Feel like slippage. If you can run it, put it in High gear, and hold both brakes. That will pull down the engine I wager!. Hopefully, JimN
 
Can't figure it out? It's a new brake/clutch pedal shaft & I put a bushing in the clutch pedal, so no slop there. I know the drive is connected because I replaced those rubber washers. It's the old pressure plate, so there are no shipping bolts. I don't think the Rockford pressure plate will fit backwards. The free play is good and spring pressure is firm. Something is not letting it dis-engage completly. I'll figure it out eventually.
 
If the driven disk hub gets a bit stuck on the splines if the clutch shaft, or is running in wear grooves from the prior clutches, it will definately rub its new face on the flywheel and drag. Sometimes enough to keep shifting from happening. A bent hub from a bit of juggeling with insertion will also cause the same issue.
Keep us informed, JimN
 
Possibility #2 is probably right Jim. It's up on jacks - no wheels or tires. (or brake pedals yet). I just got the engine running yesterday, and when I tried the gears for the first time, the axels did spin, but there's no "umph" without wheels or ground contact - just didn't seem right. I'll put the brakes to it to see if there is slippage in the clutch or my head.

Thanks
 
Gene's reference was to the friction disc, not the pressure plate. The splined hub of the disc is not symmetrical, it projects further on one side than the other, like a short neck, if that's the way to describe it. The shorter side goes toward the flywheel, the longer side toward the tranny. If you've got that in backwards, it could keep your clutch from releasing.
 
DRC: How many springs does the pressure plate have? I've changed a lot of clutches in my day, and every time it has been the complete assembly; pressure plate, clutch disc, release bearing and pilot bearing or bushing. I've never seen a pressure plate that wasn't in as bad shape as clutch disc, some worse. It's just not worth splitting tractor a second time.

I'm not sure what you have wrong, suspect it may be adjustment. I don't think you have the clutch disc in backwards, that usually locks them up and you can't adjust it enough to make clutch release.
